HOOK FOR DRUM-HEAD STRAINERS.

SPECIFICATION forming part of Letters Patent No. 382,124, dated May 1,1888.

Application filed August 3l, 1887. Serial No. 248,425. (No model.)

To all whom it may concern:

Be it known that I, GEORGE VAN ZANDT, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Drum-.Head Strainers, of whichthe following is a specification.

My invention is particularly directed to the improvement of the hooks orhangers employed in drum-head strainers for connecting the cords orwires with the hoops, and applied at points where it is desirable toprovide bearings for the cords and wires and connect the same with thehoops.

The hanger characterized by my improvementis made from a comparativelywide sheetmetal strip, which is bent and folded upon itself alonga linetransversely to its length, so as to provide along the line of fold acomparatively long bearing for the straining-wire of a drum-headstrainer. The two folds or leaves of such folded sheet-metal strip arebrought together iiatwise, and lie in close j uxtaposition to oneanother from the fold in which the straining-wire is received, wherebythe wire can be, and desirably is, closely clasped by the sheetmetalstrip along the line of fold which serves to provide at one end of thehanger a rigid connection between the same and the straining-wire. Thesheet-metal strip, thus folded upon itself so as to iuclose and embracethe Wire at one end of the hanger, is also bent to provide at theopposite end of the completed hanger a curved lip, which is designed tohook onto the outer edge of the hoop of the drum. The hanger thus formedlies fiatwise against the hoop and closely follows the transversesectional outline of the same, thereby avoiding objectionableprojections, which, particularly along the outer edge of the hoop, wouldbe of considerable annoyance to the drummer. The

j completed hanger thus made from a sheet-metal strip can from theprimary operation of cutting the strip from a metal sheet to thecompletion of its two bends (or fold and bend) be economically andrapidly made by a suitable press or dies; and since it is made ofsheetmetal the width of the strip can'be such as to provide the hangerwith broad bearings, respectivel y, for securing the wire and for engagking 'the edge of the hoop without undesirably increasing the weight ofthe hanger.

At apoint between the hook end and the line of fold the two leaves ofthe sheet-metal hanger are connected together by astud or rivet, whichserves to maintain such two folds or leaves in a fixed relative positionand prevents one leaf from slipping upon the other under the strain towhich the hanger may be subjected, it being observed that' sucharrangement also places no particular limitation upon the length of the,inner leaf, which is next adjacent to the hoop so long as such leaf isengaged bya stud or rivet passing through both leaves.

It is further desirable to attach the hanger to the hoop at somepredetermined point,in order that an unskilled person in replacing abroken drum-head with a new one may not experience the difficulty ofdeciding as to the exact points where the hangers should be applied. Tosuch end the stud or rivet which passes through the two leaves of thesheetmetal hanger is extended through the hoop, thereby firmly securingthe hanger in place.

In the drawings, Figure 1 represents in side elevation a portion of adrum with a portion of the drum-head straining device applied andembodying my invention. Fig. 2 represents a section taken transverselythrough one of the hoops with my improved construction of h'angerapplied thereto.

The sheet-metal hanger A is formed from a metal strip of appropriatelength and width, bent or folded upon itself so as to bring its twofolds or leaves 'flatwise together, and provide along the line of fold acomparatively long straight bearing, a, wherein the wire Bof thestraining device is received and rigidly held. The strip thus foldedupon itself to clasp or embrace the straining-wire is also bent toprovide the curved lip a', whiehisadapted in contour to the outerrounded edge of the drumhoop D, said engaging-lip being somewhat in thenature of l a' broad hook hat in cross-section, the width of such hookor engaging-lip serving to provide the hanger with a somewhat extendedbearing on the edge portion of the hoop.

C indicates the stud or rivet, which passes through the two leaves a2and c3 of the sheet- IOO metal hanger, therebypreventing any slipbetween them. This rivet is also extended through the hoop, as in Fig.2, whereinits inner end is shown headed upon a washer, E.

As herein shown, the two leaves or folds of the folded metal strip arebent to form a curved lip, which engages upon the edge of the hoop; butit may be observed that in view of the rivet-connection between the twoleaves and the width of the strip of which the hanger is formed theembracement of the hoop-edge by the inner leaf, a", is not a materialfeature, since the curved lip portion of the outer leaf, a2, isofsufficient strength for all practical purposes.

It will be seen that this hanger corresponds in its generalconfiguration to the cross-see tional outline of both the rounded outeredge and the outer side of the hoop, and that as the hanger is made ofcomparatively thin sheet metal the presence of all objectionableprojections is avoided. The rivet, while serving to prevent the leavesfrom slipping upon one another under the strain of the tightened wiresB, further serves to maintain the hangers in definite locations, wherebythey are prevented from shifting their position on the hoops. It willalso be observed that the frictional eontact between the two leavesfurther assists in keeping them in place, and, further, that the outerleaf orfold binds against the inner leaf or fold and serves to clamp thesame against the hoop.

The wires B are rigidly clasped by the hangers, and are herein shownattached at their ends to adjustable tension devices similar to thetension devices embodied and forming the subject-matter ofa claim in myapplication, Serial No. 246,921, for Letters Patent now pendingin theUnited States Patent Office, although no limitation is herein placedupon the partieular construction of adjustable tension devices employed.

As hereinbefore stated, these hangers can be readily and economicallyproduced by ma- 45 chinery, and when made and applied as hereinbeforeset forth will be found light, durable, and of an exceedingly neatappearance.

"What I claim 'as my invention isl. In a drum-head strainer, a hangerfor the 5o straining-wire, formed of a sheet metal strip folded backupon itself to provide along the line of fold a bearing, a, wherein thestraining- Wire is clasped and bent to form a curved lip,

a', which engages upon the edge of the hoop, 55 the two leaves ofsuchfolded strip being brought closely together flatwise from the fold,substantially as and for the purpose set forth.

2. In a drunrhead strainer, a hanger for the straining-wire, formed of asheet-metal strip 6o folded upon itself to receive and clasp thestraining-wire along the line of fold and bent to provide a curved lipwhich engages the edge ofthe hoop, the twolea'ves of such sheetmetalhanger being brought together from the 65 fold and held against slippingupon one an other by a rivet, substantially as set forth.

3. In a drum-head strainer, a hanger for the straining'wire, formed of asheet-metal strip folded upon itself to receive and clasp the 7ostrainingwire along its line of fold, and bent to provide a curved lipwhich engages the edge of the hoop, the two leaves ofsueh sheetmetalhanger being brought together from the fold, and combined with arivetpassing through 75 both leaves and extending into the hoop,substantially as and for the purpose set forth.
